摘要
当前环保冷媒R410A风冷冷(热)水机组逐步大面积用于生产热水,对比此类机组运行条件及系统与普通空调的差异性的变化,研究发现其对四通阀应用存在差异性;本文着重从四通阀材料、结构及控制等方面进行研究并通过实验加以验证,得出在四通阀应用方面的相关结论。
Recently the air-cooled chiller （heat pump） which uses R410A as refrigerant has been widely applied for production of hot water. Compared operational conditions and systematic differences of this kind of units, this pa-per figures out there are much application diversities for the four-way valve. Then, this paper makes large studies on the material, structure and control of the four - way valves and proves this conclusion through experimental tests. In the end, this paper summarizes some conclusions on application of the four-way valve.
